摘要： A sludge or slurry physical stabilizing method combines coarse particles with a slurry of fine particles to generate a composite slurry having a substantially predetermined ratio of coarse particles to fine particles. The composite slurry can then be diluted, flocculated and/or dewatered. Superabsorbent polymer (SAP) is mixed in with the dewatered composite slurry in an amount effective to produce a shear stable, non-segregating conveyable composition of sufficient strength to enable pumping, transport and placement at a mining site or tailings disposal site.
